Wow. Novell have built Hula , a calendar and mail server. Web-front end (decent JS/DOM scripting GMail-style thing), plugins for Thunderbird, Sunbird, Evo, the works. Bloody good job Novell. This is a critical project for Linux corporate acceptance (and the discussion we had on LugRadio nearly a year ago underlines the point; we said then that there was nothing that could replace Exchange, except Chandler which didn’t work, and when we recently picked that discussion up again we said that there still was nothing). The Kolab people might say that they’ve been doing this for ages, but there doesn’t seem to be much Kolab acceptance. Hula looks fantastic. I’ll be looking at this in more detail.
